The house's electrical system - how it works

The house's electrical system - how it works

That we have electricity in the house is obvious. It is so given that we do not even think of anything other than in the few occasions "the power goes", but then we usually stand completely hand-held. If the power outage lasts more than a few minutes and hits a larger area, this is so sensational that the following day results in black newspaper headings in the style of "Sweden Lambs ..."

The reaction may seem excessively cool, but we think it is closer Maybe, after all, quite natural, although we only look at what is happening in our own, close surroundings. It is not just the light that goes out. In most households, we can no longer even cook a cup of coffee to calm down. It's a crossbone for most, naturally simple features. The dishwasher and the washing machine stops, the fridge turns off, the freezer produces no cold and we have our own well, we can not even drain a rinse of water because the pump no longer works. If it's winter it will soon be cold house - whether the home is heated or we are burning with oil. The TV picture goes out and the online radio is silent.

If the stream is on a fall or winter night, we start immediately fidding with matches and candles and tread us to the power station to see if the main fuse is complete. Is it it will not be long before we do what we may never else take before: call on the nearest neighbors to ask if it's dark even with them.

That we get so handled depends, of course, on power outages outside the house neither can nor do anything to help the situation. A little piece of hair Can you say that we are as ruthless as people were about 200 years ago. The only known way to generate electricity was to rub, for example, an amber. By the way, that's why we're talking about electricity. The word comes from electron, which is the Greek expression for just amber.

The only thing that really separates us from the late 18th century people is that we have made ourselves completely dependent on electrical power - that from different sources of power reaches us through the so-called service line that our local power plant has dug into the street or the ground outside our house.

Feel at times sometimes if the stopper hoods are hot. It may be a sign of overload, but it may also be because they are not tight enough. Unnecessarily long wires are always in trouble. A practical solution is a cable wind, which allows you to roll out as long a cord as necessary for, for example, different work with the drill machine. There are cable wires with four sockets. A practical tip is to hang up the cable wall on the wall.

Worth knowing

From 1 July 1989, the previous mandatory SEMKO approval is optional. However, it is still expected that most manufacturers of electrical appliances will use the test to use the S-brand guarantee. Nowadays, Swedish standard voltage for ordinary household appliances is 230/400 volts.
